What mid-pack Cimarron Electric Coop filings show
Cimarron Electric Coop is a member-owned electric cooperative operating in Oklahoma under EIA identifier 3478. It reports service to approximately 18,996 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 51 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.
In 2023, the average Cimarron Electric Coop customer experienced 106.8 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 1.10, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 32.1 minutes; the difference from the headline 106.8 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Cimarron Electric Coop, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 2843.2 to 106.8 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Cimarron Electric Coop's other reported years.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
